PHP socket_bind() - Address already in use?

Question

PHP

I have the following sequence of actions:

socket_create();
socket_bind();
socket_accept();
socket_close();

I start this server, as it were, I connect to it, the server shuts down (without cycles). Everything is fine, I
start the server immediately for the second time, but it pops up

PHP Warning:  socket_bind(): unable to bind address [98]: Address already in us

I'm waiting somewhere for 30 seconds (some kind of timeout), I run it again - everything is OK,
but why is that? I close the socket after myself

Answer 1

When an application dies, the system does not release the socket immediately (by default), it goes into TAIM_AWAIT.
If you want to explicitly indicate that immediately after the socket is closed, it can be opened immediately, you need to specify the SO_REUSEADDR option
